I wanted to write to you straightaway to thank you for a wonderful job. The design was very clever and the work by Martin has been excellent. He is so good and patient. I felt sorry for him when he discovered that the shower piping connection (installed some 20 years or so ago by the then Southern Electric) was wrong – something of course that the plumber who installed the replacement shower a few months ago might have worked out had he checked it after ‘completing’ the job rather than before. Fortunately Martin’s ingenuity worked it all out and there was no need to undo any of the tiling/other. He is definitely a treasure.
